Labor Day in Tennessee usually brings warm afternoons, mild mornings, and a mix of sunshine with the chance of late-summer rain. Daytime highs often reach the 80s across much of the state, and evenings cool off into the 60s.
It’s honestly one of the more comfortable holiday weekends for outdoor plans, though you might still run into some humidity and scattered storms.
You’ll notice the weather shifts depending on where you go. West Tennessee tends to feel hotter and stickier, while the eastern mountains stay a bit cooler, especially after dark.
That difference can shape your plans, whether you’re heading out for a lake trip, catching a football game, or hiking in the Smokies.
If you know the typical weather patterns for this time of year, you can prepare for both sunshine and the occasional shower.
With the right mindset, you’ll get the most out of the long weekend, no matter where you end up in Tennessee.
Typical Weather Conditions Around Labor Day
Around Labor Day, Tennessee serves up warm afternoons and cooler mornings, with a decent chance of scattered rain. The air usually feels humid, but sometimes drier breezes roll in after a cold front.
You’ll see plenty of sunshine, though clouds and thunderstorms can still pop up.
Average Temperatures During Labor Day Weekend
Daytime highs usually land in the mid-80s°F in Memphis and the upper 70s°F in Knoxville, with Nashville somewhere in between.
At night, temps drop into the low to mid-60s°F, so mornings feel more comfortable than the afternoons.
Heat waves don’t happen as often by early September, but every now and then, you’ll see the upper 80s°F or even low 90s°F. Sometimes a cold front sweeps in, and daytime highs only reach the 70s, bringing a little taste of fall.
If you’re planning outdoor activities, expect those warm afternoons, but maybe toss a light jacket in your bag for the cooler evenings.
The swing between day and night temps can feel pretty noticeable in eastern Tennessee.
Humidity and Comfort Levels
Humidity really shapes how the weather feels. In early September, dew points typically hover in the mid-60s°F, which can make things feel muggy, especially in Memphis and Nashville.
Knoxville, thanks to its higher elevation, usually feels a bit less humid.
When a cold front moves through, the humidity often drops fast, and the air turns much more comfortable.
You might wake up one day to sticky air and, by the next, feel a real difference.
You should expect some stickiness during the weekend. If humidity bothers you, mornings and evenings are usually the best times to be outside.
Precipitation Patterns and Rainfall
Labor Day weekend can bring a mix of dry spells and scattered rain. Tennessee cities average 7 to 10 wet days in September, so showers or storms aren’t rare.
Thunderstorms pop up more in the afternoons, once the heat builds. These storms can drop brief downpours, thunder, and lightning, but they usually move on pretty quickly.
Rainfall totals for September average 2.5–4.5 inches, depending on where you are.
If you’re planning anything outdoors, it’s smart to keep an eye on the radar. Even if the weekend starts dry, sudden showers can sneak up, especially in the western and central parts of the state.
Sunshine and Cloud Cover
Expect a good dose of sunshine around Labor Day, but clouds often build as the day goes on.
In Nashville and Memphis, you’ll see clear or partly cloudy skies about 65–70% of the time in early September.
Knoxville tends to have more clouds, so you might notice a difference there.
The sun rises around 6:30–7:00 a.m. and sets close to 7:15–7:30 p.m., giving you about 12–13 hours of daylight.
That’s plenty of time for outdoor plans, even if some clouds roll through.
Thunderstorms can block out the sun for a bit, but skies usually clear up again after the rain.
Most days still offer a few hours of direct sunshine, even if the weather’s a little mixed.
Day-By-Day Weather Breakdown
Temperatures around Labor Day in Tennessee often sit in the low to mid-80s during the day and drop into the 60s at night.

Weather for Saturday
Saturday usually starts off warm and humid, with morning lows near 65–70°F in Nashville, Memphis, and Knoxville.
By afternoon, highs reach 82–86°F. It’s comfortable, but still muggy if you’re out and about.
Cloud cover can change a lot, but the risk of pop-up thunderstorms grows as the afternoon goes on.
These storms bring quick bursts of heavy rain, thunder, and gusty winds.
They don’t stick around long, so it’s smart to plan outdoor stuff earlier in the day to dodge any disruptions.
Rainfall is usually light unless a storm hangs around. Winds stay light, averaging 5–8 mph, so the air can feel pretty still in the humidity.
If you’re headed to a festival or outdoor event, bring some water and maybe a light rain jacket.

Humidity hangs on, and you’ll probably feel it most during midday.
Rain chances pick up, especially in the afternoon. Scattered thunderstorms are common, and some may last longer than Saturday’s quick showers.
Severe weather isn’t typical, but lightning and heavy downpours can definitely mess with outdoor plans.
You’ll still get some sunshine between storms, so expect a mix of bright skies and passing clouds.
Winds usually stay light, but gusts can pick up near storms. If you’re driving, watch for wet roads and lower visibility during heavier rain.
Labor Day Monday Forecast
Labor Day itself usually settles into a pretty steady pattern. Morning temperatures near 68–70°F rise into the mid-80s by the afternoon.
Humidity stays high, making it feel warmer than the thermometer says.
Rain chances run moderate to high, with afternoon thunderstorms likely in a lot of areas.
These storms can be scattered, but they often mess with travel and outdoor gatherings.
Storms can form quickly, so checking radar before you head out is a good idea.
If the skies clear after a storm, you can expect a pleasant evening with temps dropping into the upper 60s.
Winds stay gentle, except when storms roll through—then gusts can briefly top 20 mph.
Regional Variations Across Tennessee
Weather conditions shift a lot across Tennessee as Labor Day nears.
Differences in terrain and geography create unique temperature ranges, rainfall amounts, and storm risks in each part of the state.
You’ll find warmer, more humid air in the west, milder weather in the center, and cooler, wetter conditions in the east.
West Tennessee Weather Overview
In West Tennessee—think Memphis and the Mississippi River Valley—daytime highs usually hit the mid to upper 80s°F around Labor Day.
Nights cool to the mid-60s°F, but the humidity sticks around.
Rainfall averages about 2 to 3 inches in September, with 7–8 days of measurable precipitation.
Thunderstorms are common, especially in the afternoon and evening. These storms bring heavy downpours, plenty of lightning, and quick bursts of gusty winds.
The flat landscape lets warm air from the Gulf move north easily, so muggy days happen more here than elsewhere.
You might also notice stronger winds, especially before or after a storm passes through.
Middle Tennessee Weather Overview
In Middle Tennessee—Nashville and the Highland Rim—average highs hover near the low 80s°F in early September.
Overnight lows drop into the low to mid-60s°F, so evenings feel a bit more comfortable than in the west.
Rainfall is similar to the west, with about 3 inches for the month and 8–10 wet days.
Afternoon thunderstorms do happen, but they tend to be short. Still, heavy rain can pop up in certain spots, so you’ll want to stay flexible with plans.
Humidity’s moderate, and the rolling hills help break up some of the heat.
Skies are often partly cloudy, and you’ll notice clearer days becoming more common as fall approaches.
This region really sits between the warmer west and cooler east.
East Tennessee and Mountain Areas
East Tennessee—including Knoxville and the Smoky Mountains—runs cooler.
Highs usually stay in the upper 70s to low 80s°F, and lows dip into the upper 50s to low 60s°F. Higher elevations can feel even chillier, especially at night.
Rainfall is a bit heavier, averaging 3 to 4 inches in September.
You can expect 9–12 days with measurable precipitation, and thunderstorms show up more in valleys than on the peaks.
Mountain weather changes fast, so you might go from sunny to rainy in just a few hours.
Humidity drops at higher elevations, so the air feels nicer than in the west.
Fog often forms in the mornings, especially in the Smokies, and that can cut visibility for travelers.
The mountains also get more rain, making this the wettest part of Tennessee in late summer.
Weather Hazards and Safety
Labor Day weather in Tennessee usually means warm afternoons and the chance for sudden storms.
You’ll want to be ready for both heavy rain with lightning and long stretches in the sun.
Thunderstorm Risks and Lightning
Thunderstorms stay pretty common in late summer across Tennessee.
Afternoon heat and humidity can spark fast‑forming storms that bring heavy rain, gusty winds, and plenty of lightning.
These storms can show up with little warning, especially in the mountains or open farmland.
Lightning is the biggest hazard. Head indoors as soon as you hear thunder.
Shelters like houses, cabins, or enclosed vehicles offer the best protection.
Stay away from open fields, tall isolated trees, and metal objects like fences or bleachers.
Flash flooding sometimes happens in low‑lying areas when rain gets intense.
Roads can get slick or even impassable for a while.
If you’re driving, don’t try to cross water covering the pavement. Even shallow, moving water can sweep a car away.
Keep a weather app or portable radio handy for quick updates on storms and warnings.
Heat and Sun Exposure Precautions
Temperatures around Labor Day often reach the 80s or low 90s °F.
With high humidity, it can feel hotter than it really is.
Spending too much time outdoors can lead to dehydration, heat exhaustion, or heat stroke if you don’t take care.
Drink water regularly, even if you’re not thirsty. Go easy on alcohol and caffeine since both can make you lose fluids faster.
Lightweight, light‑colored clothes help keep you cooler.
Sunshine can get pretty intense, especially midday. Use broad‑spectrum sunscreen with SPF 30 or higher, and put more on every couple of hours—especially if you’re sweating or swimming.
Sunglasses and a wide‑brimmed hat help too.
Plan your hardest activities—hiking, sports, whatever—for the morning or evening, when it’s not as hot.
Take breaks in the shade or find some air‑conditioning to give your body a rest.
Travel and Outdoor Planning Tips
Temperatures in Tennessee around Labor Day usually run warm during the day, with evenings that feel a lot better.
Be ready for sun, possible afternoon thunderstorms, and heavier travel as folks hit the road for the holiday weekend.
Best Times for Outdoor Activities
Daytime highs usually hit the mid-80s °F. That can feel pretty hot if you’re outside for long stretches.
Early mornings and evenings bring cooler air, often in the 60s or low 70s °F. Those times just feel better for hiking, biking, or walking tours.
Humidity adds to the heat. So, pace yourself and take breaks when you can.
Bring water, sunscreen, and a hat to cut down on sun stress. If you like fishing or boating, mornings are calmer and the lakes or rivers stay less crowded.
Afternoon thunderstorms pop up a lot in late summer. Storms can develop fast, so check the forecast before heading out.
A quick storm might blow through in under an hour. Still, if the sky darkens, get off the water and away from open areas right away because of lightning.
Quick tips for outdoor comfort:
- Best hours: sunrise to mid-morning, late afternoon to dusk
- Pack: sunscreen, water, light rain jacket
- Watch for: thunderstorm alerts and sudden cloud build-up
Travel Considerations for Labor Day Weekend
Labor Day weekend brings heavier traffic on interstates and popular routes. If you’re driving, expect delays near Nashville, Knoxville, and Memphis.
Starting your trip earlier in the day usually helps you dodge the longest backups.
Hotels and campgrounds fill up fast. Book your lodging early, especially if you want to stay near state parks or festival spots.
Parking at major attractions can be tight too, so give yourself extra time.
Air travel gets busy, with higher ticket prices and crowded airports. Get to the airport early and, if you can, keep your return plans flexible.
Weather can change in a hurry. It’s smart to have a backup plan for indoor activities like museums or historic tours.
Pack both light clothing for sun and a rain layer for storms. That way, you’ll stay comfortable no matter what.
How Labor Day Weather Compares to Other Months
Labor Day weather in Tennessee usually marks a turning point between summer heat and the cooler days of fall.
Temperatures, humidity, and rainfall patterns all shift in noticeable ways compared to midsummer and the months that follow.
Comparing to July and August Weather
July and August bring the hottest weather in Tennessee. Average highs reach 87–91°F in Memphis, 88–89°F in Nashville, and about 87°F in Knoxville.
Lows often stay in the upper 60s to low 70s, so nights can feel warm and there’s not much cooling off.
Humidity really peaks during these months. In July, you might get 20–27 muggy days depending on where you are.
Afternoon thunderstorms show up a lot, with rainfall totals around 3–4 inches.
By early September, temperatures ease up a bit. Highs average 82–84°F in Memphis, 82°F in Nashville, and 81°F in Knoxville.
Nights cool off more, dipping into the low to mid-60s. Humidity drops, and rainfall trends a little lower than in midsummer.
So, Labor Day feels less stifling than July or August, but you still get some summer warmth.
Looking Ahead to October and Fall
By October, the weather changes a lot. Highs drop into the low 70s, and lows fall into the 50s.
This shift makes outdoor activities way more comfortable, with far fewer muggy days.
Rainfall decreases too. Knoxville averages 2.6 inches in October, while late summer brings 3–4 inches. Nashville and Memphis see a similar drop, so October ends up being one of the drier months.
Skies clear up more often. In Nashville, the chance of clearer skies rises to 64% in October, compared to about 55% in April or May.
You get more sunny days and less haze, which just feels nice.
By mid to late October, cooler evenings really let you know fall’s here, and it feels pretty different from the warmth of Labor Day.
Winter Months: January and February Overview
Winter really shakes things up. In January, Tennessee usually sees highs around 48–50°F. Lows drop to about 32–34°F.
February edges up just a bit, with highs climbing to 52–54°F. Lows hang out in the mid-30s.
You might get some snow, but it’s never much. Nashville and Knoxville each pick up around 1.5–1.7 inches in both January and February. Memphis gets a little less.
Rain keeps coming, with totals close to 3.5–3.9 inches per month.
Daylight feels scarce, averaging just 10 hours in January. By September, you get more than 12 hours, which feels like a big difference.
Winds pick up in winter, too. Memphis averages 10 mph this time of year, compared to just 6–7 mph in the summer.
